Take the buns out of the freezer and place in the refrigerator overnights, the buns should not be frozen anymore.
Turn on the oven to 350F. Take a piece of aluminum foil, place an even layer of buns on the aluminum foil, and fold the foil over the buns. Fold in the sides, try to make a small package.
Heat it for approximately 25-30 minutes. Be careful, it is going to be hot. To check the buns, take one out of the foil and cut it open to see if it is warm, time and temperatures may vary depending on the oven. Enjoy!
If you want the crust crunchy-er, take it out of the aluminum foil and bake for about 10 more minutes.
